Tb aZZ whom it may concern: i

Be it known that I, JOSEPH M. BLAKE, a

in the county of Erie and State of New York, have invented certain new and useful Improvements in DumpingWVagons for Lumber; and I do hereby declare the following to be a full, clear, and exact description of the invention, 'such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked'thereomwhich form apart of this specication.

My invention relates, particularly, to that class of dumping-wagons which are -especially adapted for carrying lumber.

In my application, filed simultaneously with this, for a dumpingwagon for coal, Snc., the serial number of which is 217,302, I Vhave shown and claimed a frame adapted to be attached to the bolsters of a wagon and provided with special attachments adapted for operation with the boxin the operation of dumping same. In my present application I employ, broadly, the same frame; but, as I do not employ a box, the operative parts attached tov the frame are essentially different, and it is for these differences in construction and operation'that I seek protection.

I will now proceed to describe the manner in which I have carried out my invention.

In the drawings, Figure 1 shows a side elevation of a lumber-wagon with my improved construction attached. Fig. 2 is a top plan view of the frame detached, and Figs. 3 andft are detached detail views.

Referring to the drawings, a a are the wheels, a the front bolster, a2 the rear bolster, and a3 the reach, of a wagon of ordinary construction, to which my improved construction is tobc applied. As in my other application above operative parts, .which frame is adapted to be directly applied to the front and rear holsters, a and a2, of the form of wagon shown, or any other well-known form. Of this frame, b b The front ends of these sills are securely bolted to the front holster,`a/, and the rear ends of the sills are secured to the bearing-plates havbolster, a2.

ing sides, openends and top', and closed bottoni. These 'bearing-,plates cc, with their contained sills, are securely bolted to the rear Projecting from these bearingplates c c are the journalboxes dd, through which passes the shaft e, adapted to turn loosely therein. Upon this-shaft e ,is thelong central driving-roller, f, and the small side rollers, ff, rigidly secured to o r integral with the shaft, the small rollcrsff being hetweeu the sides of the journal-boxes d d.

At the forward ends of the sills b b are the two friction rollers g g, extending entirely across the frame'and having their ends flanged, as at g. These friction or carrier rollers are kept apart and supported in their proper working position by the crosspieces g2 g2, and

arranged centrally upon these crosspieces g2 g2 are the keepers g g, extending downwardly and inwardly, their ends riding in the side grooves, g4 9*, in the outer faces of the sills. The stops g5 g5 upon`the sillsb limit the niovement of the=rollers g g.

Upon the outer end of the shaft e is arranged a double ratchet and pawl lever, similar to the one shown in my other application before referred to, which operates to turn the shaft e, and with it the rollersf and ff, in either direct-ion. Of this lever, his the handle secured to the casing h', within which are the pivoted dogs or pawls h2 h2, having their inner ends adapted for engagement with the ratchetwheel k, and having their outer ends provided with cam-faces for engagement with the canivfaces of the thumb-nuts h3 h3, which operate to throw the inner ends of the pawls in and out of engagement with the ratchet-wheel k, so that the shaft e can be turned in either direction or held rigidly by the handle h.

The operation of my improved apparatus just described is as follows: The lumber shown at lis piled upon the wagon so that it will lie at the forward end of the wagon upon the friction rods or rollers g g and at its rear end upon the larger rollers, f and f f', the usual side stakes, m, keeping the load from falling oii' at the sides. When it is desired to dump the load, the double ratchet and pawl lever is adjusted as shown in Fig. 3, and by working the handle h up and down, the shaft e and its rollers are caused to turn in positive rotation.

Asthey turn, the lum'ber is moved backward by its friction thereon until it will tip by reason of its own gravity into the position shown in dotted lines in Fig. 1, and rthe wagon being pulled forward from under the tipped load such load falls to the ground. The forward frietionrollers, f/ g," operating with the rear moving rollers as explained, make it an easy and simple matter to rapidly I nove the load so that it can be dumped.

It will be remembered that while my improved lumberdump herein described and my improvedeoaldump described in the application before referred to are sonewhat similar in certain particulars, notably'in the operatinglever and the' frame for attachment to the bolsters, and to a smaller degree in the forward friction devices, yet the differ" ences in details of construction 'and operation adapt each form of dump for separate and independent functions.

I'claiml.

1. In a dumping-wagon for lumber, a. frame adapted to be secured directly tothe fron-t and rear holsters of the wagon,frictionrollers resting upon the top face of and extending transverse] y across the sills, and adapted to reeiprocate therealong for the pu rpose of supporting the front of the loa-d while at rest and during ing ends of said side plates, one or more ro1l ers mounted upon said shaft, and means, substantiallyas described, for rotating said shaft and roller.

2. In a dumping-wagon for lumber,a frame consisting of the side sills, b b, with suitable strengthening erosspieees, such frame being adapted for direct attachment to the bolsters of the wagon, the fretion-rollers g g', with their guiding-frames g2 g, controlled in their movement by the grooves g* inthe sills b b,and the rear moving rollers, f andff, turned in bearings in the frame by the lever h to move the load of lumber backward, substantial] y as shown, and for the purpose stated.

In testimony whereof Ihavjesigned my. name to this specication in the presence of two subscribing witnesses.; y.
